Honest questions because I don't know how it all works.
Biden is clearly, and was while in office, living with a severe loss of cognitive functions. It doesn't take a genius to figure out those closest to him covered it up and used the media to spread lies and misinformation.
So how do you do anything about it IF you even have some venue to pursue a case? Who ran the country while a vegetable was nominally in charge? (Yes, we know but what can someone prove?)
I'd love to see people go down even if it was a charge for abusing the elderly, but is there even a mechanism to address a president AFTER they are out of office?
